NAME

6       osmium-renumber - renumber object IDs
7

SYNOPSIS

9       osmium renumber [OPTIONS] OSM-DATA-FILE
10

DESCRIPTION

12       The objects (nodes, ways, and relations) in an OSM file often have very
13       large IDs.  This can make some kinds of postprocessing difficult.  This
14       command will renumber all objects using IDs starting at 1.  Referential
15       integrity will be kept.  All objects which appear in  the  source  file
16       will be in the same order in the output file.  IDs of objects which are
17       not in the file but referenced from ways or relations are  not  guaran‐
18       teed to be in the correct order.
19
20       This  command  expects  the  input file to be ordered in the usual way:
21       First nodes in order of ID, then ways in order of ID, then relations in
22       order of ID.  Negative IDs are allowed, they must be ordered before the
23       positive IDs.  See the osmium-sort(1)  man  page  for  details  of  the
24       ordering.
25
26       The  input file will be read twice, so it will not work with STDIN.  If
27       you are not renumbering relations (ie.  if the  option  –object-type/-t
28       is  used  with nodes and/or ways but not relations) the input file will
29       only be read once, so in that case it will work with STDIN.
30
31       To renumber the IDs in several files, call  osmium  renumber  for  each
32       file and specify the -i or --index-directory option each time.  See the
33       INDEX FILES section for more details.
34
35       You must never upload the data generated by this command to  OSM!  This
36       would  really  confuse  the  OSM  database because it knows the objects
37       under different IDs.
38

OPTIONS

40       -i, –index-directory=DIR
41              Directory where the index files for mapping between old and news
42              IDs are read from and written to, respectively.  Use this if you
43              want to map IDs in several OSM files.  Without this option,  the
44              indexes  are  not  read  from or written to disk.  The directory
45              must exist.  Use `.' for the current directory.  The files writ‐
46              ten  will  be named nodes.idx, ways.idx, and relations.idx.  See
47              also the INDEX FILES section below.
48
49       –show-index=TYPE
50              Print the content of the index for TYPE (node, way, or relation)
51              on STDOUT.  Each line contains the old ID, a space character and
52              then the new ID.  Any other options (except –index-directory/-i)
53              are ignored if this option is used.
54
55       -s, –start-id=FIRST_ID or FIRST_NODE_ID,FIRST_WAY_ID,FIRST_RELATION_ID
56              Set  the  first  ID that should be used.  If the ID is positive,
57              IDs are counted upwards, if the ID is negative, they are counted
58              downwards.   This can be set to either a single ID which is used
59              for all object types or a comma-separated list of three IDs used
60              for the first node, way, and relation, respectively.  If this is
61              not set, IDs for all object types start at 1.
62
63       -t, –object-type=TYPE
64              Renumber only objects of given type (node,  way,  or  relation).
65              By default all objects of all types are renumbered.  This option
66              can be given multiple times.
67

COMMON OPTIONS

69       -h, –help
70              Show usage help.
71
72       -v, –verbose
73              Set verbose mode.  The program  will  output  information  about
74              what it is doing to STDERR.
75
76       –progress
77              Show  progress bar.  Usually a progress bar is only displayed if
78              STDOUT and STDERR are detected to be TTY.  With  this  option  a
79              progress  bar  is  always  shown.  Note that a progress bar will
80              never be shown when reading from STDIN or a pipe.
81
82       –no-progress
83              Do not show progress bar.  Usually a progress bar  is  displayed
84              if STDOUT and STDERR are detected to be a TTY.  With this option
85              the progress bar is suppressed.  Note that a progress  bar  will
86              never be shown when reading from STDIN or a pipe.
87

INPUT OPTIONS

89       -F, –input-format=FORMAT
90              The  format  of the input file(s).  Can be used to set the input
91              format if it can't be autodetected from the file name(s).   This
92              will  set the format for all input files, there is no way to set
93              the format for some  input  files  only.   See  osmium-file-for‐
94              mats(5) or the libosmium manual for details.
95

OUTPUT OPTIONS

97       -f, –output-format=FORMAT
98              The  format  of  the output file.  Can be used to set the output
99              file format if it can't be autodetected  from  the  output  file
100              name.   See  osmium-file-formats(5)  or the libosmium manual for
101              details.
102
103       –fsync Call fsync after writing the output file to force flushing  buf‐
104              fers to disk.
105
106       –generator=NAME
107              The  name and version of the program generating the output file.
108              It will be added to the header of the output file.   Default  is
109osmium/” and the version of osmium.
110
111       -o, –output=FILE
112              Name of the output file.  Default is `-' (STDOUT).
113
114       -O, –overwrite
115              Allow  an  existing  output  file  to  be overwritten.  Normally
116              osmium will refuse to write over an existing file.
117
118       –output-header=OPTION
119              Add output header option.  This  option  can  be  given  several
120              times.   See  the  libosmium manual for a list of allowed header
121              options.
122

INDEX FILES

124       When the -i or –index-directory option is specified, index files  named
125       nodes.idx, ways.idx, and relations.idx are read from and written to the
126       given directory together with a file called start_ids that contains the
127       start IDs set with –start-id/-s.
128
129       This  can  be used to force consistent mapping over several invocations
130       of osmium renumber, for instance when you want to  remap  an  OSM  data
131       file and a corresponding OSM change file.
132
133       The  index files are in binary format, but you can print the indexes in
134       text format using the –show-index option:
135
136              osmium renumber -i idxdir --show-index node     >nodes-index.txt
137              osmium renumber -i idxdir --show-index way      >ways-index.txt
138              osmium renumber -i idxdir --show-index relation >relations-index.txt
139

DIAGNOSTICS

141       osmium renumber exits with exit code
142
143       0      if everything went alright,
144
145       1      if there was an error processing the data, or
146
147       2      if there was a problem with the command line arguments.
148

MEMORY USAGE

150       osmium renumber needs quite a bit of main memory to  keep  the  mapping
151       between  old  and  new  IDs.   It is intended for small to medium sized
152       extracts.  You will need more than 32 GB RAM to  run  this  on  a  full
153       planet.
154
155       Memory  use  is  at least 8 bytes per node, way, and relation ID in the
156       input file.
157

EXAMPLES

159       Renumber a PBF file and output to a compressed XML file:
160
161              osmium renumber -o ch.osm.bz2 germany.osm.pbf
162
163       Renumbering Germany currently (spring 2016) takes less than three  min‐
164       utes and needs about 3 GB RAM.
165
166       Renumber  a PBF file starting the node IDs at 1 (and counting upwards),
167       the way IDs at 100 and the relation IDs at  -200  (and  counting  down‐
168       wards.
169
170              osmium renumber -o renumbered.osm.pbf -s 1,100,-200 athens.osm.pbf
171
172       Renumber an OSM file storing the indexes on disk:
173
174              osmium renumber -i. -o renumbered.osm data.osm
175
176       then rewrite a change file, too:
177
178              osmium renumber -i. -o renumbered.osc changes.osc
